Fox News’ Greta Van Susteren says she is “delighted” Sarah Palin is back as a Fox News contributor and that the former Republican vice presidential candidate will be “part of the national debate.”

“I am delighted to have her back at Fox,” Van Susteren told POLITICO in an email. “She has a big impact (check out the number of Facebook followers! 3.5 million!) and should be part of the national debate.”

And, Van Susteren noted, “It is free promo for Fox since it will drive her TV critics crazy! They are obsessed with her!”

Palin will appear on Fox News daytime and primetime programming, starting with an appearance on “Fox & Friends” on June 17, according to a press release. She also will be a contributor to Fox Business Network.
